Subject: [PATCH v3 5/6] mmc: sdhci-acpi: Disable write protect detection on Toshiba WT10-A
Date: Wed, 10 Apr 2024 21:16:38 +0200	[thread overview]
Message-ID: <20240410191639.526324-6-hdegoede@redhat.com> (raw)
In-Reply-To: <20240410191639.526324-1-hdegoede@redhat.com>

On the Toshiba WT10-A the microSD slot always reports the card being
write-protected, just like on the Toshiba WT8-B.

Add a DMI quirk to work around this.
